ROMAN T. KANSKI, OF NEW YORK, N. Y.

PROTECTIVE SETTING FOR METALLIC BODIIS IN CONCRETE.

To all whom it may concern:

Be it known that I, ROMAN T. KANsKI, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Im rovements in Protective Settings for Metallic Bodiesin Concrete, of which the following is a specification.

This invention relates to protective settings for metallic bodies in concrete, and its object articularly is to provide means for defending bolt heads, bridge anchors, bars and rods kgenerally that are buried in hard earth or concrete and are subjected to the deteriorating action of moisture or vagrant electrical currents from any source.

This invention consists in the special construction and arrangement of glazed earthenware blocks, cups, sleeves and the like surrounding the metallic bodies buried in the concrete, the said construction and arrangement being show-n in the accompanying drawings of which Figure 1 represents a vertical section of a mass of concrete and the protective coverings of a bolt shank and head. Fig. 2 represents a vertical section of a body of concrete and shows the nut and the end of the bolt, and the construction of the rotective covering when the exposed end o the bolt is to be covered by masonry. IFig. 3 shows the construction l'or protecting an anchor plate and the bolt rod extending therefrom, that ortion of the rod passing into the atmos ere beyond the concrete being unprotected? Like reference letters designate like parts throughout the description and drawings.

A bolt A is held wlthin the mass o f concrete B by having constructed a glazed earthenware block C formed to receive the head a of the bolt. The depression or cavity c in the block C is covered by the glazed earthenware cap D, and the sleeve d projecting u wardly and inclosing the shank of the bo t may be formed integrally with the cap D. The joint between the cap D and the block C is sealed by means of any waterproof packing E, such as rubber fabric or the like.

Upon the surface of the concrete there rests the column plate or base plate of any1 sort marked F. The bolt passes upwardly through the plate F, and the joint between the bolt,the plate F, the concrete, and the sleeve d, is suitably scaled b the waterproof acking G.

bolt A and having its edges resting u on the Patented .Tune 2,' 1908.

and head within the sleeve d and the block C is filled preferably with. neat cement H.

In Fig. 2 a glazed earthenware cup J is shown inverted over the nut and end of the rubber packing G. The cu J is emp oyed in situations where the end 0i) the bolt is to be covered by masonry K, especially, in the case of concrete blocks, sandstone, soft brick or the like. 7

In' Fig. 3 the extremity of the bolt or rod is illustrated as lprojecting beyond the surface ofthe concrete and into air. The shank of the bolt rod, of any length, is protected by the jointed, glazed earthenware sleeves L and M, and packing l and lmis introduced to seal the joints against moisture. vPacking N is likewise employed if desired to seal the joint between the lower sleeve M and the cap D of the block C. The block C has its cavity c formed to receive the head a of the bolt, and an anchor late O, and the cavity is filled about the olt head and plate with neat cement 7L. Otherwise the construction is the saine as already described.

The block C, with its cap D having the integral sleeve d, thecup J, and the jointed sleeves L and M, are all constructed as stated of glazed earthenware. Therefore, the metal bodies are not onlysecurely protected against the action of moisture, but, they are equally insulated from any external electrical effects whatever, and their life correspondingly lengthened with conse uent extension of the period of security of t 1e structure of 'which they form a part.

Having. now described my invention and explained the mode of operation, what I claim isl. A device of the character described, comprising a headed fastening, a glazed earthenware block provided with a cavity, a glazed earthenware cap adapted to close the cavity, a glazed earthenware sleeve extending from the cap and adapted to surround 100 the shank of the fastening passing through the cap, waterproof means arranged to seal the joint between the cap and block, and Waterproof means arranged to seal the joint between the bolt and sleeve at the outer end 105 of the sleeve, substantially as described.

2. A device of the character described, comprising a ,headed fastening, a glazed earthenware block rovided with a cavity adapted to receive t e head of the fastening, 110

a glazed earthenware cap adapted to close the said cavity, a glazed earthenware sleeve extending from the cap and adapted to surround the shank ofy the fastening passing through'the ca the. sleeve being larger 1n diameter than tV e said shank, cement filling within the said sleeve'laro'und the shank of the fastening, waterproof means arranged to seal the joint between the cap and block, and

waterproof means arranged to seal the joint,

j cavity, a glazed earthenware sleeve extending from the cap and adapted to surround the-shank of the fastening passing through the cap, waterproof means arranged to seal the'joint between the cap and block, waterproof means arranged to seal the joint between the bolt and sleeve at the outer end of the sleeve, and a cup adapted to be inverted over the exposed end ofA the bolt, the edge of the cup resting upon the said waterproof sealing means last mentioned, substantially as described. v

4. A device of the character described, com rising a headed fastenin a glazed eart enware block provided Wit a'cavity, a glazed earthenware cap adapted to close the cavity, va glazed earthen are 'ointed sleeve extending from the cap l d a apted to Vsurround the shank of the fastenlng passin throu hthe cap, Waterproof means arrange to sea the joint between the ca and block, and waterproof means arrange to seal the joint between the bolt and sleeve at the outer end of the sleeve, substantially as described.

In testimony whereof Iaflix my signature in presence of two witnesses.
